For its seasonal changes, the rose garden, the Serpentine, the Serpentine gallery, the Summer pavilions, the café etc.

Probably my favourite building in the city, and right in the heart of it. There are always interesting events happening here, across art and music, and you can drink in the courtyard during summer

An Amazonian blend of plants and vines spill from it's interiors, complimenting the concrete architecture that surrounds it. A nod towards films such as Logan's Run, the conservatory forms an almost utopian sci-fi environment.

An obvious choice but no 'best of London' list is complete without the Barbican

This is one of the only buildings in London that can lift depression. Each concrete block in the building is hand cast and hand hammered. Certainly the best bannisters in town.
